GENERAL NETWORKING
• Methods of Defending a Network
– Firewalls
• Networking devices (routers) that check traffic coming into a
private network
• Needs to be complete and properly configured to ensure
protection
• Good protection for general networking traffic, but specific traffic
will still get through.
– DMZs
• Network space between two firewalls
– VPNs
• Provides encrypted access from outside a network.
• Current versions aren’t reliable enough and aren’t useful against
“slow” attacks.
